Impact of an additional rupture of the residual membrane on labor timing

Official title: Impact of Early Rupture of the Residual Membrane on Latency Before Labour Begins

Run by Centre Hospitalier le Mans · NCT07301957 · Data updated 2026-11-12

This study tests whether intentionally rupturing the remaining membrane after it has already broken can change when labor starts in women who haven’t gone into labor on their own.

Is this trial a fit for you?

Likely a good fit

Adults with a single pregnancy, cephalic presentation, ruptured membranes with a remaining intact membrane, and no spontaneous labor within 12 hours.

Probably not a fit

Patients whose labor timing is unaffected by the intervention or who experience complications from the procedure may not benefit.

What this trial studies

This interventional study explores whether a deliberate rupture of the residual membrane affects the latency to labor and the need for induction in women with prelabor rupture of membranes. Eligible participants are adults with a single pregnancy, cephalic presentation, and ruptured membranes but no spontaneous labor within 12 hours. The intervention involves an additional rupture of the residual membrane, with monitoring for labor onset and induction decisions at 24 or 48 hours depending on the center. The goal is to determine if this approach shortens latency to labor without increasing maternal or fetal infection risk. Prior literature on rupture of membranes has focused on frequency and timing of induction, with antibiotic prophylaxis reducing infection risk, and this study aims to address an unanswered question in this area.

Why it matters

Potential benefit: If successful, this approach could shorten the waiting period before labor begins and reduce the need for induction.

How similar studies have gone: There is limited prior research specifically addressing additional rupture of the residual membrane; results from pilot work suggested an effect but this remains relatively novel.
